Does anyone have a part number for the C206 body connector? I have been in to the dealers today and they could not find it on their microfiche.

Are there any other GM cars WITHOUT the LS1 that uses this plug? maybe i can get one at the local pull a part. I know they do not have anything LS powered

I used the 04 GTO pcm, bcm, pim and throttle control. I used a two speed Lincoln Mark VIII fan and wired the low speed wire from the bcm to the low speed relay and the high speed wire from the pcm to the high speed relay. Works perfect.

Mark VIII fan on my 69 bird. Has never been on high speed yet. I also got the Hollister relay system. Very well made product here are a few pics.

Mark VIII two speed fan


Hollister Relay setup. This is a really robust system with high quality relays and wires. They added an extra relay to activate the fan when the A/C is on





Installed with a PRC radiator

I was going the Mark VII fan route and canned it because the factory relays could not handle the load of the fan. I ended up buying a 4th gen rad and using the factory fan setup. I have the setup if anybody is interested for $100

Can anyone direct me to a similar depiction/identification of the 2006 LS2 GTO harness connections?

Thanks.

Bringing this one out of the grave.. So will it be ok to not use plug#8 (throttle relaxer) and #11. It has voltage for injectors so thats what concerns me.
